One of the toughest questions I get when helping customers select products for their new home or remodel is "What kind of toilet should I choose?" When it comes to functionality, Kohler has the “Revolution 360” flush, Toto has the “Tornado” flush, American Standard has the “VorMax” flush, and Mansfield has the “Summit 3” flush. Which is the best? Which is the most reliable? Which will flush consistently without needing a plunger or a bowl brush?
